I have an established website of 20+ years (a ".net" TLD).
I own the .com / .uk TLDs for this name, too. I notice on the control panel of these names, there's an option to point the domain names to an existing site.
Is it safe for me to do this? So, my .net TLD will remain my core site, but if someone accidently typed ".com", it'll redirect to the correct site.
I was worried Google could see this as duplicate, or could cause other issues?
